SASH-SUPPORTING PLATFORM FOR GLAZIERS- Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed July 3, 1905. Serial No. 268,077.

To a/ZZ whom it may concern.-

Be itknown that I, FREDERI K J. PErERs,'a citizen of the United States, residing at Milwaukee, county of Milwaukee, and. State of Wisconsin, have invented new and useful Improvements in Sash-Supporting Platforms for Glaziers, of which the following is a specification.

My invention relates to improvements in revolving sash-supporting platforms for glaziers.

The object of my invention is to provide a revoluble platform which may be quickly and readily secured to the top of the table for. revolubly supportinga window-sash While the panes of glass are being secured therein.

The construction of my invention is explained by reference to the accompanying drawings, in which Figure lrepresents a side view of my sashsupporting platform in position for use upon a table of ordinary construction, the supporting-table being shown in vertical section. Fig. 2 represents a top view of my device supported upon a table. Fig. 3 represents a view from the lower side of the sash-supporting platform; and Fig. 4 represents a side view of the sash-supporting platform with parts folded together, so as to occupy less space when not in use.

Like parts are identified by the same reference-figures throughout the several views.

1 represents the central portion of the platform, which is revolubly connected with the top 2 of the table 3 by the bolt 4 and clamping hand-nut 5. To prevent the platform 1 from wabbling upwardly and downwardly or being inclined at an angle to the supportingtable top, I provide the under side of said platform with a plurality of rollers 6, which are connected with the platform 1 by brackets 7 and roller-supporting trunnions 8, whereby the platform is rigidly supported on all sides and is adapted to resist the downward pressure upon the same by the glazier in the act of securing the panes of glass in the sash, while said rollers permit of the platform 1 being freely revolved in one direction, so as to bring all parts of the sash within convenient reach of the glazier as he is doing the work, and the necessity of moving to different sides of the table or of lifting and turning the sash, as heretofore, when puttying the panes of glass in a window-sash is avoided.

It will be understood that when a glazier is 5 in the act of applying putty or other adhesive substance to a window-sash a lateral or side pressure is given to the sash in one direction as the putty is being spread along the marginal edge of the panes of glass. This lateral 6o pressure, itis obvious, will have a tendency to revolve the platform 1 around its central retaining-bolt in the direction that such pressure is applied. To prevent the platform 1 from being thus revolved by the lateral pressure of the operator in the act of spreading the putty, 1 have provided the table-top 2 with an annular ratchet 9, and l have also provided the platform 1 with a pawl 10, which is pivotally connected at its upper end to the platform 1 by the pivotal bolt 11 and-bolt-retaining bracket 12, while the lower end of said pawl is adapted to engage in the teeth of the ratchet 9, and thus prevents the platform 1 from being turned by the lateral pressure of the operator in the act of spreading the putty, as previously described, while the inclination of said pawl to the teeth of the ratchet is such as to permit said platform 1 to be freely revolved in the opposite direction at the will of the operator.

1 have shown the platform 1 formed of a plurality of pieces pivotally connected together by hinges 13.

14 is an annular sleeve which is interposed between the platform 1 and the annular ratchet 9 and is retained in place between said parts by the bolt 4:. 15 is a hook of ordinary con-' struction which is pivotally connected with one of the folding sides ofthe platform by 0 the bolt 16 and is adapted when said folding parts of the platform are brought together to engage the opposing bolt 17, whereby said parts of the platform are retained in their folded position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a glaziers table, the combination of a stationary table-top; a revoluble platform; I means for connecting said revoluble platform at its center with said supporting-table top;

a plurality of rollers connected with said revoluble platform and adapted to support the same from said table-top; an annular ratchet form in the opposite direction, all substanconnected with the upper surface of said statially as and for the purpose specified. I0 tionary table-top; a pawl pivotally connected In testimony whereoflaflix my signature in with said platform, said pawl being adapted the presence of two witnesses.
